The influence of Ambroxol on peroxidative processes in lung and plasma in dogs after pulmonectomy.

Abstract

The purpose of the studies was to determine the effect of Ambroxol on the activity of antioxidant enzymes and on the glutathione level as well as the intensity of the peroxidative processes in the lung tissue, alveolar macrophages and plasma in dogs after unilateral pulmonectomy. On the 2nd and 6th day after the surgery the activity of antioxidant enzymes and the glutathione level were studied in the remaining lung. The levels of the lipid peroxidation products were determined in the analogous system. In both examined groups the increase in the antioxidant enzyme activity and the lipid peroxidation product levels was observed in the remaining lung after the surgery. In Ambroxol-treated animals the statistically significant increase in the antioxidant enzyme activity was noted while the intensity of peroxidative processes was found to be lower. This fact may suggest that Ambroxol stimulates the resistance of the lung tissue to the free radical activity and inhibits the lung peroxidative processes in dogs after pulmonectomy.
